- Footnotes separator rather than headline to get around i18n - Warn on footnote redefinition - Do not export footnote definitions at point of definition, only in the footnote section. - Do not automatically exclude Footnotes section to get around possibly hiding other content of such a section - and i18n. The user has the choice of explicitly hiding the section via a :noexport: tag. and some other refactoring
